To provide a method for forming a boron-containing thin film, by which a uniform boron thin film with good adhesion can be formed on the surface of a processing object, and also to provide a multilayer structure. An electrolysis apparatus includes an anode 1, a processing object 2 serving as a cathode, an electrolytic vessel 4, and a molten salt electrolytic bath 5. A variable power supply 6 is connected between the anode 1 and the processing object 2. The variable power supply 6 is configured to be capable of changing a voltage or current waveform during the electrolysis process. Current of an appropriate pulse waveform is applied in the molten salt for electrolysis to form a uniform boron thin film 3 within the processing object 2 having a complicated shape.

The object of the invention is to provide a process for producing an organic solid electrolyte capacitor which is diminished in leakage current, and an apparatus for use in practicing the process. The process includes the steps of completing a capacitor element by forming a dielectric oxide film over an anode body of valve metal and subsequently forming a cathode layer of solid conductive organic material over the oxide film, subjecting the capacitor element to an aging treatment, and forming a shell around the capacitor element. The apparatus, which is an aging apparatus for such capacitor elements, comprises a box for accommodating a plurality of capacitor elements, a conductive buffer layer provided inside the box, a conductive holding member disposed on the box for attaching thereto the outer end of anode lead of each of the capacitor elements, with a silver paste layer of the element in contact with the buffer layer, a current limiter connected to the buffer layer for restricting the current to be passed through the capacitor element to not greater than a predetermined value, and a power source having positive and negative electrodes connected to the holding member and the current limiter, respectively.

In a satellite communication system including a plural small earth stations (3-8), a relay earth station (2) and a satellite (1), information transmission is undertaken by primary modulation of carrier wave, and transmission of operation status of each small earth station (3-8) is carried out by secondary modulation of said carrier wave. Primary modulation may be BPSK or multiphase PSK (MPSK), and secondary modulation may be PSK, ASK or FSK. Said operation status may be receive signal quality in each small earth station, and the relay earth station (2) may adjust transmit power to said small earth station such that the receive signal quality at small earth stations satisfies desired criteria irrespective of rain attenuation.
摘要:
Dense carbon films are deposited on a conductive substrate by placing the substrate acting as anode in a molten salt electrolyte bath containing a source of carbide ion and applying DC current across the substrate and a counter electrode acting as cathode also placed in the molten salt electrolyte bath. The carbide ions are electrochemically oxidized to deposit a carbon film on the surface of the substrate.

Dense carbon nitride films are electrochemically formed on a conductive substrate by placing the substrate acting as cathode in a molten salt electrolyte bath and applying DC current across the substrate and a counter electrode acting as anode also placed in the molten salt electrolyte bath. Carbonate ion and nitrate ion are concurrently reduced to deposit carbon nitride films on the substrate.

The present invention provides an improved gate valve system for cutting off a fluid flowing through a pipe. The gate valve system includes a gate valve and at least one member. The gate valve includes a seal member exhibiting an elastically deformable property for sealingly contacting the inner surface of the pipe, and a support member for receiving said seal member and movable in the perpendicular direction to the flowing direction of the fluid between the outside and inside of the pipe for timely bringing said seal member into a sealing contact with the inner surface of the pipe. The at least one expansion member is deformable, but is not substantially subjected to the volume variation even under pressure. The at least one expansion member is embedded in the seal member in such a manner as to expand the seal member laterally outwardly to the inner surface of the pipe upon receiving pressure effected by the sealing contact between the seal member and the inner surface of the pipe.

A shift lock system for an automatic transmission is arranged to make it unfeasible to cancel the shift lock without a tool. The shift lock system includes a cancel lever for moving a shift lock member such as a rotary bush from a lock position for locking a shift lever in the park position to an unlock position against the force of a return spring, a cancel rod for operating the cancel lever, and a plug member which is normally fastened with the cancel rod to a support member by a screw fastener so that the cancel rod is immovable. The plug member can be loosened by a tool such as a screw driver. When loosened, the plug member allows a canceling operation by allowing the cancel rod to be moved.
摘要:
A fragment of the gene for the hemagglutinin neuraminidase (HN protein) of human parainfluenza Type 2 virus (PIV-2) and materials containing such fragment. The fragment is complementary to the gene RNA for the PIV-2 HN protein and contains the entire coding regions for the PIV-2 HN protein. The fragment is useful as a test agent or a therapeutic agent for PIV-2 infections.

A buzzer damping sound producing device in which a fundamental frequency pulse signal is applied to a buzzer to produce a damping sound with a predetermined period. The device includes a variable duty pulse generator which produces a fundamental frequency pulse signal repeatedly, the duty ratio of which is gradually decreased per predetermined period. The fundamental frequency pulse signal thus produced is applied to the buzzer to operate the buzzer, whereby buzzer damping sounds different in period and frequency can be produced readily.
